We're dividing 780280 by 27 
The aim is to understand the frequency of 27 in 780280.

Moving on to step 1:
If we divide 7 by 27, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 27

Advancing to step 2:
78 divided by 27 is 2 with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 54 away from 78, we end up with 24.
Fetch the next digit (0) from the dividend, attach it to 24 and continue: 240 / 27

On to step 3:
27 can be fit into 240 8 times, resulting in a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 28.0
If we subtract 216 from 240, we get 24.
Take the next digit (2) from the dividend and append it to 24, then repeat: 242 / 27

Moving on to step 4:
27 goes into 242 8 times with a remainder of 26.
Put 8 as the next digit of the answer. 
Result so far: 288.0
Deduct 216 from 242 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 27

Going ahead to step 5:
When dividing 268 by 27, we get 9 with a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 2889.0
If we take 243 away from 268, we end up with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 27

Advancing to step 6:
If we divide 250 by 27, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 28899.0
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 27, we get 2 and a remainder of 16.
The number 2 becomes the next digit in our result. 
Result so far: 28899.2
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
160 divided by 27 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 28899.25
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 9:
When dividing 250 by 27, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 28899.259
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 10:
70 divided by 27 is 2 with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 28899.2592
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 11:
If we divide 160 by 27, we get 5 and a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 28899.25925
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
27 can be fit into 250 9 times, resulting in a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 28899.259259
Subtracting 243 from 250 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
27 can be fit into 70 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 28899.2592592
Deduct 54 from 70 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 14:
The number 27 fits into 160 5 times, leaving a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 28899.25925925
Deduct 135 from 160 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 28899.25925925 and a remainder of 2.5e-08.
